This is the relevant part of the log file:

drm couldn't attach to the card which resulted in a KMS failure.

No idea why, since I don't use KMS.  Maybe someone with more
knowledge can help you out.

Do you have the drm module loaded?  I couldn't see anything
in the trace which indicates that drm was loaded by X.
